The present invention relates to receiver holders'for telephone instruments, the object being to provide an exceedingly simple structure that will support the receiver at the ear of the user of the instru1nent,'thus leaving both hands free. A further ob ect -is to provide a device in which the receiver is'readily adjustable todifferent posit ons, so that it may be desirably located.

' In the accompanying drawings:

Figure 1 is a side elevation ofthe attachment in a position to hold the usualhook down,

Figure 2 is a front view of the same, Figure 3 is a side elevation with therecei'ver in position for use, j ,Figure 4 is a detail perspective view of the ball and socket connection between the carrier arm and receiver bracket,

Fig'ure'fi is a view in elevation of the supporting bracket, I

Figures 6 and 7 are detail sectional views onthe line'6-6 and 7 7 of Figure 2.

"Th'efusual desk telephone set is illustrated, the transmitter 8 being supported on a standard 9 and the receiver being designated 10. p The receiver-holding hook is shown at 11.

' surround and be clamped about the standardfi and having anangular jarmlli, the outer portion of which extends forwardly and upwardly. -A carrier arm 14 is pro vided with ahead 15, pivoted as shown at 16, to the free end of the arm 13, and this carrier arm is adapted to swing between a position on the hook 11 and a position in advance of the receivenas shown in Figure 3. a The head is providedwith'a circular periphery 17 fbIQkGIIbY a notch 18 forming a stop shoulder 19. A'leaf spring 20,;secured to the arm 13, has a' curvedterminal portion 21 that bears upon the, curved portion 17 of the head '15, said portion 21 being adapted to vdrop into the notch 18 and the end being abutted against by the sh oulder19 when the carrier arm 14 is swung to its forward tionally engaged by a pair of ijaws 23, form In the embodiment of the invention dis-- ing a part of the receiver supporting bracket. These jaws are mounted on a sec tional ring 24 that surrounds the receiver 10.

The jaws are drawn toward each other by a V 'bet'ween'for the arm 14 to permit of thefree universal"adjustment of said members 23 on said ball 22 relative to the arm 14. The members or jaws 23 project laterally from the ball 22 to form a support for the'sectional ring 24 in which the receiver-is secured, and the outer end of one jaw is provided with an inwardly directed flange interengaging the outer edge of the other jaw to maintain the members 23 in separate relation. When the screw 25 is tightened the opposing jaws '23 frict-ionally engage opposite sides of the ball 22 and are retained thereon against removal. The ring or annular member 24 is arranged upon and transversely ofthe projecting portions of the jaws 23 in close relation to the upper ed s thereof and in off-set relation to the ba 1 22 so that the plane of the inner portion of said ring is substantially tangential 22 inbalanced'relationthereto and as close to the ball or pivoted connection as possible.

This arrangement permits of the vertical adjustment of the receiver so that the operative end thereof swings through vertical arcs extending substantiall parallel with and in close relation to the ead of the per- 'son using the device and so that the operative end of the receiver as it is adjusted vertically about its pivot will not swing away from the ear, of the user; Whether the outer end otthe receiver is swung vertically or horizontally the "radii" of the arcs described thereby are substantially the same or equal because the receiver is positioned substantiallyat-or "in as, close a position as possible to the pivotal connection' It will be evident that this device can be mounted on the usual telephoneinstrument and the ordinary receiver can besupported forwardly the spring frictionally rides on": the periphery 17 of the head 15, and thus affords some resistance to the movement of the arm, and the foremost position of the arm and receiver is determined by the shoulden 19 abutting against the free end of the spring. cated in convenient relation to the ear of the user. of the telephone, the position of the receiver being readily variable in any direction by reason of the ball and socket mounting. V i

From the foregoing, it is thoughtthat the construction, operation and many advantages of the herein described invention will be apparent to those skilled iii the art, with out further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. is

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A telephone attachment comprising a bracket member and means for mounting the same on a telephoneinstrument, a receiver carrying arm member pivoted to the bracket member and adapted to move between a position on the receiver hook and a position in advance of the same, one of said members having a head provided with a smooth friction surface terminating in a stop shoulder, and afriction spring carried by the other member and bearingagainst the frictionsurface, said spring abutting against the stop shoulder when .the carrying arm in its advance position to holdit therein and bearing againt the smooth friction surface during thetravel of sa d arm to and when it is located on said receiver book.

2. A telephone attachment compris ng a bracket -member, means for securing the same in position relative to a telephone instrument, a receiver carrying member pivoted at the lower end thereof tosaid bracket member, andadapted to swing about its pivot between a position on the receiver hook and a position above said pivot in advance of the same; one of said members having a friction surface adjacent said pivot terminating in a recess, and a resilient member interposed between said receiver carrying member adjacent to the pivot thereof and said bracket member and continuously bean.

ing against said friction surface and retained under tension thereby to frictionally resist the pivotal movement of said arm as the same s swung betweensaid positions, and

adapted to be released to'enter said recess In this position the receiver is 10- as said arm'is moved to its advanced position for yieldably locking the same in said position against movement towards its hook engaging position.
